Problematic solids corresponding to sanitary towels, plastic bags, textiles and wooden are being discovered more and more often in wastewater. Pumping and sewage treatment vegetation are therefore increasingly reaching their limits; models get clogged up and break down.
In instances when low lifecycle prices are playing an ever extra necessary position, HOMA Pumpenfabrik presents an energy environment friendly and reliable solution for areas where a excessive delivery head is required, but at the same time, a diverse range of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection permits effective operation via a robust cutter system. Thanks to the usage of extremely durable chilled chrome cast iron, the principle components which are topic to probably the most stress perform reliably even with abrasive substances similar to sand. HOMA will be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices are becoming increasingly important in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and dependable pumps that attain high supply heads with nice efficiency.” With its new Alligator chopper pump collection, which may even be out there as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our goal was to achieve excessive delivery pressures in the medium circulate rate vary,” stories Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and more energy saving motor than in other pumps in the identical operating vary was enough. To achieve this, HOMA developed a brand new cutter system that effectively shreds and removes giant portions of numerous solids corresponding to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater via surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which can be equipped with its own cutter. This design permits the two central components to work together to catch solids, break them down and finally remove them from the suction area via integrated grooves within the put on plate.
To enable larger effectivity with out compromising on chopping efficiency, the blades of the impeller also curve strongly backwards. As a result, in the 50 Hz version, a circulate rate of as a lot as a hundred thirty m³/h and a supply head of as a lot as fifty seven m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to 20 kW, a flow price of up to a hundred and forty m³/h and a delivery head of up to 82 m are potential. The suction cowl mounted on the pump housing may additionally be used to adjust the chopping hole between the impeller and the wear plate with the aid of six set screws. “ เกจวัดแรงดันถังลม of our new Alligator series, which is on the market for moist properly installation in addition to dry installation, is its great effectivity and efficient cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to achieve not only the finest possible effectivity values in the operating range required for these kinds of wastewater applications, but also to minimize back lifecycle prices overall, HOMA attaches nice importance to low-maintenance operation along with efficiency. The impeller and wear plate, that are the components topic to the most stress, are manufactured from extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics were optimally designed for the working vary utilizing computational fluid dynamics (CFD) to increase efficiency and to eliminate any risk of solids building up, which can negatively impression performance and result in pricey pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids in the waste water and transport them away, saving each power and upkeep prices because of their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water purposes that require excessive supply strain, but on the identical time need to cope with many alternative kinds of solids.”
HOMA might be presenting the new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other innovations, similar to the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
